Answer:

Step 3, because the solution should also include all the values for x between the two given values

Step-by-step explanation:

step 1

we have

$y_1=\left|x-4\right|$

$y2=1$

step 2

The graph in the given problem

step 3

Identify the solution when $y1\leq y2$

$\left|x-4\right|\le1$

using a graphing tool

The solution is the interval -----> [3,5]

see the attached figure

All real numbers greater than or equal to 3 and less than or equal to 5

therefore

The first step in which the student made an error is step 3

calculate the means and the standard deviation of the following set of data 4.578g, 4.581g, 4.572g, 4.573g, 4.601g, 4.577g. stat

AfilCa [17]

Answer:

68% Confidence interval = [4.5752, 4.5848]

95% Confidence interval = [4.5688, 4.5918]

Step-by-step explanation:

Sample mean (X) = 4.580

Sample Standard Deviation (S) = 0.01065

Sample size (n) = 6

$T_{(5)}$ for alpha/2 0.84 = 1.1037

$T_{(5)}$ for alpha/2 0.975 = 2.5706

68% Confidence interval = $[x-T_{(5)}\frac{S}{\sqrt{n}}, x+T_{(5)]\frac{S}{\sqrt{n}}]$ = [4.5752, 4.5848]

95% Confidence interval = $[x-T_{(5)}\frac{S}{\sqrt{n}}, x+T_{(5)}\frac{S}{\sqrt{n}}]$ = [4.5688, 4.5918]

A=c+(-10) Solve for c in terms of other variables.

True [87]

To do this we need to move 10 to other side. To accomplish this you just need to add 10 to both side since (-10)

so
A+ 10 = c -10 + 10
we get
A+ 10 = c

lets say it wasn't -10 but positive 10.

A = c + 10 then we would subtract 10 from both sides

A -10 = c + 10 - 10
we get
A - 10 = C

Kyra observed that 85% of the students at a library liked reading mystery stories. If 30 students at the library did not like re

boyakko [2]

First calculate that numeric value. It cannot be done immediately without calculations.

if 85% of studends liked mystery that means that 100% - 85% = 15% didnt like.

Those 15% are 30 that were given in text. Now we can calculate this using proportion:

15% 30 students
85% x students

we use cross multiplication:
15*x = 30*85
x = 30*85/15
x = 170

Answer is 170
